Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical devices, and more specifically, to a hook structure for a dual-headed infusion set. Background Technology
[0002] Intravenous infusion is a medical procedure that delivers medications or solutions into a patient's body via a vein for purposes such as treatment, fluid replacement, or nutritional support. It is a common medical procedure used to treat various diseases, replenish fluids, and provide nutritional support. During intravenous infusions, medical personnel must strictly adhere to disinfection and safe operating procedures to ensure patient safety and effective medication delivery.
[0003] The inventors believe that current intravenous infusion procedures involve medical staff directly hanging the infusion bottle on the infusion stand in the infusion room. When the patient needs to move, the bottle is usually removed and carried along (e.g., to the toilet), which is inconvenient to store after disassembly. To address these issues, a double-ended infusion set hook structure is provided.
[0004] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To address the problems mentioned in the background art, this application provides a hook structure for a double-headed infusion set.
[0006] The technical solution for the double-headed infusion set hook structure provided in this application is as follows:
[0007] A double-headed infusion set hook structure includes a connecting block; a pair of hooks fixedly disposed at the bottom of the connecting block for hanging an infusion bag; a retaining ring fixedly disposed at the top of the connecting block; and a fastening mechanism disposed at the top of the connecting block for positioning the retaining ring, which includes a slide rod slidably disposed at the center of the top of the connecting block, an arc-shaped strip fixedly disposed at the top end of the slide rod, a movable block fixedly connected to the bottom end of the slide rod, the movable block slidably disposed inside the connecting block, and the side of the movable block being arranged outside the connecting block, and a spring passing through the middle of the slide rod at the position between the connecting block and the arc-shaped strip.
[0008] By adopting the above technical solution and through this structural design, it is convenient for patients to disassemble the infusion bottle during the infusion process, to hold the infusion bottle while walking, to avoid contaminating the infusion bottle, and to prevent the infusion bottle from falling.
[0009] Preferably, two movable rods are symmetrically arranged at the bottom of the arc-shaped strip, and the bottom ends of the two movable rods are slidably inserted into the interior of the connecting block.
[0010] By adopting the above technical solution, when the sliding rod moves up and down, the two moving rods can move up and down, thereby ensuring the smoothness of the arc-shaped strip's movement.
[0011] Preferably, a pull ring is fixedly provided at the bottom end of the moving block.
[0012] By adopting the above technical solution and setting a pull ring, it is convenient for operators to pull the moving block.
[0013] Preferably, a rubber gasket is adhered to the inner wall of the retaining ring at the position relative to the arc-shaped strip.
[0014] By adopting the above technical solution and setting rubber gaskets, the stability of the clamp connection to the infusion stand can be increased.
[0015] Preferably, a magnet is fixedly disposed on the concave surface of the arc-shaped strip.
[0016] By adopting the above technical solution and setting up a magnet, the external infusion stand can be attracted by the magnet, which further increases the stability of the clasp insertion.
[0017] In summary, this application includes the following beneficial technical effects:
[0018] Pulling the moving block causes the sliding rod to move downwards, which in turn moves the arc-shaped strip downwards. At this time, the spring will contract. After the retaining ring is inserted into the IV stand, the operator releases the moving block, causing the spring to extend. This causes the arc-shaped strip to move upwards and cooperate with the retaining ring, squeezing and fixing the tubing on the IV stand. The retaining ring is then assembled. The two hooks can be hung on the external IV stand through the retaining ring, and then the IV bottle can be hung on the hooks, completing the hook structure installation. Through this structural design, the fastening mechanism can be loosened directly to remove the entire hook. When walking, the retaining ring can be squeezed for easy lifting, without contaminating the IV bottle (bag) and preventing it from falling. The retaining ring can be easily hung on any size fixed hook, making it easy to remove and detach. This avoids patients repeatedly hanging IV bottles (bags), causing contamination of the IV bottle (bag) opening, falling, or even needle displacement during puncture, resulting in repeated puncture pain and reduced satisfaction.

[0023] The following is in conjunction with the appendix Figures 1 to 3 This application will be described in further detail.
[0024] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.
[0025] This application discloses a hook structure for a double-headed infusion set. (Refer to...) Figures 1 to 3 A double-headed infusion set hook structure includes a connecting block 1; a pair of hooks 2, fixedly disposed at the bottom of the connecting block 1 for hanging infusion bags; a retaining ring 3, fixedly disposed at the top of the connecting block 1; and a fastening mechanism 4, disposed at the top of the connecting block 1 for positioning the retaining ring 3. The fastening mechanism 4 includes a sliding rod 400 slidably disposed at the center of the top of the connecting block 1, an arc-shaped strip 401 fixedly disposed at the top of the sliding rod 400, a movable block 402 fixedly connected at the bottom of the sliding rod 400, the movable block 402 slidably disposed inside the connecting block 1, and the side of the movable block 402 arranged outside the connecting block 1. A spring 403 is inserted through the middle of the sliding rod 400 at the position between the connecting block 1 and the arc-shaped strip 401.
[0026] Specifically, when the retaining ring 3 is attached, the operator can pull the moving block 402 to cause the sliding rod 400 to move downward, thereby causing the arc strip 401 to move downward. At this time, the spring 403 will contract. After the retaining ring 3 is inserted into the infusion stand, the operator releases the moving block 402, causing the spring 403 to extend. This causes the arc strip 401 to move upward and cooperate with the retaining ring 3, squeezing and fixing the tubing on the infusion stand, thus assembling the retaining ring 3. The two hooks 2 can be hung on the external infusion stand through the retaining ring 3, and then the infusion bottle can be hung on the hooks 2, completing the installation of the hook structure. Through this structural design, it is convenient for patients to disassemble the infusion bottle during the infusion process, squeeze the infusion bottle when walking, avoid contaminating the infusion bottle, and prevent the infusion bottle from falling.
[0027] When removing the device, simply loosen the fastening mechanism 4 to remove the entire hook 2. When walking, pinch the retaining ring 3 for easy lifting and gripping, preventing contamination of the infusion bottle (bag) and avoiding it from falling off. The retaining ring is convenient to hang on any size fixed hook, making it easy to remove and detach. This avoids patients having to hang the infusion bottle (bag) multiple times, which could cause contamination of the infusion bottle (bag) opening, drop, or even needle displacement during puncture, leading to repeated puncture pain and reduced patient satisfaction.
[0028] Reference Figure 3 Two movable rods 404 are symmetrically arranged at the bottom of the arc-shaped bar 401, and the bottom ends of the two movable rods 404 are slidably inserted into the interior of the connecting block 1. When the slide rod 400 moves up and down, the two movable rods 404 can move up and down, thereby ensuring the stability of the arc-shaped bar 401.
[0029] Reference Figure 1 and Figure 2 A pull ring 405 is fixedly provided at the bottom of the moving block 402. By providing the pull ring 405, the operator can easily pull the moving block 402.
[0030] Reference Figure 1 and Figure 3 A rubber gasket 5 is bonded to the inner wall of the retaining ring 3 at the position relative to the arc strip 401. The rubber gasket 5 can increase the stability of the retaining ring 3 in connecting to the infusion stand.
[0031] Reference Figure 1 and Figure 2 A magnet 6 is fixedly installed on the concave surface of the arc-shaped strip 401. By installing the magnet 6, the external infusion stand can be attracted by the magnet 6, which further increases the stability of the insertion and insertion of the retaining ring 3.
[0032] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0033] The implementation principle of the double-headed infusion set hook structure in this application embodiment is as follows: When the retaining ring 3 is hung, the operator can pull the moving block 402 to make the moving block 402 drive the sliding rod 400 to move down, thereby moving the arc strip 401 down. At this time, the spring 403 will contract. After the retaining ring 3 is inserted on the infusion stand, the operator releases the moving block 402, causing the spring 403 to extend. As a result, the arc strip 401 moves up to cooperate with the retaining ring 3, squeezing and fixing the tube on the infusion stand, thereby assembling the retaining ring 3. The two hooks 2 can be hung on the external infusion stand through the retaining ring 3, and then the infusion bottle is hung on the hook 2, completing the installation of the hook structure.
[0034] Moreover, when the slide bar 400 moves up and down, the two moving rods 404 can also move up and down, thereby ensuring the smoothness of the movement of the arc-shaped bar 401.
